HOOKER SHAPEL, OF IOLA, KANSAS.

LIQUID-FUEL BURNER.

To all whom it may concern:

Be it known that I, HOOKER SHAPEL, a citizen of the United States,residing at Iola, in the county of Allen and State of Kansas, haveinvented a new and useful Liquid-Fuel Burner, of which the following isa specification` This inventon relates to liquid fuel burners of theretort type, and more particularly a burner of this type in which theretort overlies the gas or vapor flame; and it is the object of thepresent invention to provide a burner of the kind stated which is verysimple in structure, and highly eliicient in operation.

The invention also has for its object to provide improved means forstarting the retort before the burner proper is started, and also toprovide a retort which is so constructed that it can be operated with asmall fire.

Another object of the invention is to provide a burner embodying certainnovel structural details to be hereinafter described and claimed.

In order that the invention may be better understood, reference is hadto the accompanying drawing, in which- Flgure 1 is a vert-ical sectionalview of the burner and retort. Fig. 2 is a horizontal section on theline 2f-2 of Fig. 1.

The burner which is the subject of the present invention is designed forheating and cooking stoves.

The burner proper and the retort comprise chambers 5 and 6,respectively, the retort overlying the burner, and these parts beingsuitably shaped to t the kind ofstove to which they are to be applied.For heatin stoves, the two chambers will generally e cylindrical inform, and for cooking stoves they maybe made oblong, to conform to theoutline of the fire pot. It may be here stated that in use, the burnerwill be mounted inthe fire pot of the stove, it being supported thereinin any suitable manner as, for instance, on the grate.

|Ilhe top 7 of the chamber 5 is formed with an upstanding marginal ange8, and from said top also rises an upstandmg flange 9, these two flangesbeing concentricall arran ed, and the ange 8 inclosin the ange 9. Theflanges, and the top of t e chamber therebetween form anannular pan ortrou h which is for a purpose to be presently escribed. Within thatportion of the top 7 Specification of Letters Patent.

Serial No. 536,645.

of the chamber 5, which is inclosed by the flange 9, are a plurality ofburner openings 10 through which the gas or vapor escapes.

Secured to, and rising centrally from the top 7 of the burner chamber,is a post 11 on which the retort chamber 6 is supported a suitabledistance above the burner chamber. The retort chamber 6 is entered,preferably, although not necessarily, through the top, by an oil supplypipe .12, and from said chamber, pipes 13 lead to, and enter the burnerchamber 5, the last-mentioned pipes being provided for conducting thegas or vapor generated in the retort chamber to -the burner chamber. Theends of the pipes 13, within the burner chamber 5, are closed, andprovided with top openings 14 through which the gas or vapor escapesinto the chamber` The o il supply pi 3e 12 leads to a storage tank whichmay be ocated at any suitable place inside or out of the house, saidstorage tank to have suflicient elevation to give gravity pressure tothe oil.

The bottom of the burner chamber 5 is entered by an air supply pipe l5which extends to the outside of the stove and has its inlet end providedwith a suitable valve 16, for controlling the amount of air entering theburner chamber.

To the pipe 12 is connected a branch pipe 17 said branch pipe leadingto, and hav ing its discharge end so located as to. discharge into thepan formed on the top of the burner chamber 5. In the branch pipe is avalve 18, and between the junction of the branch pipe and the pipe 12,and the retort chamber 6, is a valve 19; The retort chamber 6 may alsobe connected by a pipe 2O to one or more illuminating burners 21.

To operate the burner, the valve 19 is closed, and the valve 18 openedto permit the oil to run into the pan on top of thel burner chamber 5.When a suiiicient amount of oil has run into the pan, the valve 18 isclosed, and the oil in the pan is ignited. As the pan is locateddirectly under the retort chamber 6, the latter is rapidly heated, afterwhich the valve 19 is opened, and the oil is permitted to enter theretort chamber,

chamber through the pipe 15, and the highly o' 1l inflammablev mixturethus produced issues from the openings l0, at which it burns. The flamethus producedv Will impinge against the bottom of the retort chamber'Ilhe burner herein described is simple iny structure, and can bereadily a plied to any ordinary stove. The amount o gas or vaporgenerated is readily controlled by the valve 19, and as the retortpresents a large heating surface to the burner, a smallv fire may bemaintained without stoppage of the operation of the retort.

What' is Claimed is:

1. In a liquid fuel burner, a chamber hav ing-burner openings in itstop, and a pan on said top surrounding the burner openings, a retortoverlying theveha-mber, a fuel supply pipe-.to thev retort, a vapordelivery pipe from the retort to the chamber, an

air suppl-y ppe to the chamber, and a fuel supply pipe isoharging intothe pan.

2. In a liquid fuel burner, a Chamber having burner openings in its top,spaced and concentric annular' flanges rising from the top of saidchamber, the inner flange-surrounding the burner openings, a retortoverlying the chamber, a fuel supply pipe to the retort, a vapordelivery pipe from the retort to the chamber, an air supply pipe to thechamber', andv a fuel supplyv pipe discharging on the top of the chamberbetween the flanges.

In testimony that I .claim the foregoing as my own., I have heretoaffixed my signature in the presenee of two. Witnesses- HOOKER SHAPEL.
